please some one help me to solve this problem

It looks to me like you don't have the kernel source installed.

keshavgopinath,

You need the r8169 kernel module for that NIC.
I think kernel 2.6.18 predates that NIC by a long way, so yes, you need a kernel update.

If you feel lucky, tryits harmless if it fails.

thanks, but i need to install which version of kernel is suite for me and how can i find that version of kernel pls help me

uname -r to check version of kernel
